Application filed May 11,

To all whom it may concer/n:

Be it known that I, AL NELSON, a citizen of the United States, residing at Ripley, in the county of Lauderdale and State of Ten- 5 nessee, have invented new and useful Improvements in Boll-Weevl Exterminators, of which the following is a specification.

This invention relates to insect destroyers and has for its object .the provision of a machine which is capable of use for applying poison powder to rows of cotton or other plants and which is also provided with means for sucking up and collecting punc-v tured squares, weevils and other dbris.

An important object is the provision of a machine of-this character which is provided with a fan driven by one of the wheels and operating to suck up the punctured squares and other` matter, the other wheel operating to drive a selectively usable pump device for applying'insecticide to the plants, either in liquid or powdered form, or for spraying the plants with water to make the subsequently blown powder adhere to the plants.

Another object is the provision of a device of this character which carries means for shaking the plants more or less violently for the purpose of knocking 0E the punctured squares or the like so that they may be I0 subsequently gathered up by the suction mechanism.

Another object is the provision of a device o this character which will treat two or more rows at one time and which is so con- 35 structed asto be adjustable and convenient in use regardless of whether the rows be closeito ether or far apart.

An additional object is the provision of a machine of this character which. will be simple and inexpensive in manufacture, easy to control and operate, eticient and durable in service and a general improvement in the art.

With the above and other objects and ad- 45 vantages in view the invention consists in the details of construction to be hereinafter more fully describedand claimed and illustrated\ in the accompanying drawings, in which: Figure 1 is a side elevation of the device, Figure 2 is a vertical longitudinal section, Figure 3 is a top plan view, Figure 4 is a p an view with portions omitted illustrating the drive mechanism and the shaking means, Y

Figure 5 is a sectional view taken longitudinally of the axle,

Figure 6 is a detail section,

Figure 7 is a detail sectional view through the collecting receptacle.

Figure 8 is a longitudinal section through one of the pumps, i

Figure 9 is a detail section on substantially theline 9--9 of Figure 3, Figure 10 is a detail section on substan tiallythe line 10-10 of Figure 3 `.and 'l Figure 11 is a detail view of the blower. Referring more particularly to the drawings I have shown the device as comprisin 7 a suitable sup-porting frame 15 constructe of angle iron or other suitable material and of an desired shape, this fra'me moreover inclu ing any necessary number of longitudinal and transverse bars suitably connected and reinforced ify desired by any braces which may be needed. At one end this frame is provided with a draft tongue 16 by means'of which the device may be drawn along the ground by means of draft animals, a` tractor` or the like. This frame is mounted upon an arched axle which includes telescopically engaged sections`17 and 18 which terminate in trunnions 19 on which fon the frame and carrying a fly wheel 26 and 'a sprocket 27 about which is trained a chain 28 which is in turn trained about a sprocket 29 on one of the ground engaging.

wheels .20. Mounted on the frame is a suitable supporting bracket structure 30 through which the shaft 25 extends, and inwardly of this bracket the shaft carries a sprocket 32 havngtrained thereover a chain 33 which is in turn trained about -a sprocket 34 on the shaft 24 of the blower. On lthe. shaft 31 is a clutch member adapted to be engaged by a clutch face 36 formed on asleeve 37 splined on the shaft 35 and moved by means i l provided with an outlet 39 through which air fis discharged into the atmosphere.

Mounted upon the frame 15 at some con-' venient location, preferabl rearwardly of theffan casing, is a suction ox 40 connected with the inlet 41 of the fan casing. Carried by this suction box is any desired number of depending flexible tubes 42 which terminate in suction nozzles 43 designed to be disposed immediately above the surfaceof the ground traveled over or to trail upon the ground it such be preferred. `These hose or tubes 42 are here illustrated as being supported by links 44 mounted on the frame and carrying clampsv 45 engaged upon the hose, the clamps being adj ustably mounted along the hose and held in adjusted position by suit-` able set screws orlthelike 46.

Located within the suction box is apartition 47 of wire screen which extends diagonally across the box and whichl is for the.

purpose of preventing the matter drawn up through the tubes 42 from entering the fan casin .y This suction box is prolonged downward y as shown to'provide a receptacle 48 within which weevils and punctured squares accumulate, and it is vprefbottom of this receptacle be e ui ped with ya movably mounted'door 49 cleanw ic may be easily opened to permit dbris ing out of the accumulation of therein. V In order thatthe device mayl be used for applying a poison powdento t e plants for killing any insects thereon, I provide' tanks or receptacles'O at some convenient location on the frame which tanks are provided with filling openings normally closed by caps 51. Thebottoms of.

' with outlets, designated by the numeral 52 illustrated as y powdere and connected with these lvoutlets are hose 53 terminating in discharge nozzles 54 of any preferred type, though they are here belng hollow shell like members provided with/perforations. These outlets 52 are provided with cut off valves 55 eiuipped withsuitable handles 56 by means o w 1ch the valves may be opened orclosed at will and both valves are connectedby a rod 57.

Theo` erating means for applying the poison consists of a pump 58 suitably mounted on the frame and having an air inlet 59 and an air` outlet 60, thev latter of which is connected with a branched pipe 61 which leads to both of the tanks or receptacles 50. This pump .58 is of course equipped with valves 62 and 63 located 1n the air inlet and exhaust, which valves are here illustrated as being of the flap type though it is of course tolbe understood that,

these tanks 50 are provided some other specific construction might be employed if preferred. This pump further includes a reciprocatory pistn 64 carried by a piston rod 65 which 1s connected with a wrist pin 66 on a disk 67 rotatable on a shaft 68 and carr ing a gear 69 and a clutch member 70. ecured upon the other ground engaging wheel 20 is a sprocket 71 about lwhich is trained a chain 72 which is in turn trained about a sprocket 73 on a counter-shaft 74 which carries a gear 75 meshlng with the gear A69. Splined upon the shaft 68 is a clutch member 76 grooved for receiving a collar 77 connected with an angle lever 78 which may be moved by a rod 79 operated b any desired means for throwing the clutc members 76 and 70 into or out of engagement. When these clutch members are engaged, it is quite apparent that the rotation of the ground engaging wheel will be imparted 'to the disk 67 so -that the pump 68 will be actuated to blow out the an event it is necessary first to spray the f plants with water -so that'the powder will stick. To accomplish this I provide a tank 80 having a suitable filling opening normally closed by a cap 81 and this tank is.`

provided at itsbottom with outlets 82 with which are connected outlet pipes 83 which terminate in suitable *nozzles 84 forl spray-l ing the YWater on to the plants. The outlets 82 oi the tank are equipped with valves.

85 movable into open or closed position by means of handles 86 either of which may be operated as both valves are connected by a rod 87:

The operating means for spraying the Water comprises a pump 88 suitably mounted on'the'frame and having a check valve in let 89 and a check valve outlet 90, the latter being connected with the tank 80 by a pipe 91. The pump further includes a piston 92 carriedby aV piston rod 93 connected with a wrist pin 94 on a disk 95 carried by a counter-shaft 96 upon which is splined a' clutch member 97 having a grooved collar connected with an anglelever 98. The angle lever may be moved by any suitable lever means, not shown, connected with a rod 99 whereby the clutch member mayl be shifted into and out of engagement with a similar V'clutch member 100 rotatable on the shaft 96 and carried by a gear 102 which meshes with the gear-'7 5 so as to be constantly driven jl thereby. y

In orderto knock weevils and punctured uares oil of the growing plants, I provide a rod 103 which is mounted transversely of the forward portion of the frame and' secured to this rodis a plurality of downwardly and lolo lll

. wliic rearwardly extending arms 104 which may be adjusted if desired owing to the fact that they are carried bysleeves 105 mounted on the rod 103 and. held in adjusted position by set screws 106. These armsl04 are arranged in spaced parallel relation and are serpentine or zigzag in shape, so that as the machine is drawn along with these rods engaging against opposite sides of the plants in a row the plants will be shaken violently from side to side which will naturally re' sult in shaking 'oil' weevils and punctured squares.

In the operation of the device it is of course apparent that the suction fan is used for githering up all the dbri which dbris is co ected within the receptac e 48 andsub` uentl destroyed by any desired means. If

esire at anytime the sprayin mechanism may be thrown into operation y engaging the clutch members 97 and 100 so that the plants will be spra d'with water prior to the application o the powdered poison which is applied by throwing the pump 58' into operation throu h en gement of the clutch members 70 and 76. Ihstead of spraying the plants with plain water and subsequently applying the powdered poison it is to be noted that insecticide in liquid form .may be sprayed upon the plants directly,

this bein entirely optional with the user.

From t e foregoing description and a stud of the drawin it will be apparent that have'thus provided a simply constructed and easil o erated` and controlled machine will eiliciently perform its purpose and :which will consequently greatly improve the crop of cotton or the like inasmuch as the removal ofthe weevils will promote healthy growth of the plants.

While I have shown and described the preferred embodiment of the invention it is of course to be understood that I reserve the right to make such anges ,in the form,

construction andarrangement of vparte as' will not depart from the spirit of the inven-- tion or the scope of the subjoined claims.

Having thus described my .invention I Y claim: f l n 1. A boll weevil destroyer, a wheel supported frame, collecting means thereon, and means for "knocking the weevils from the plants, comprising a rod mounted transversely'at the forward end of the frame, and a plurality of shaker rods carried by said rod and including downwardly inclined portions terminating in horizontally disposed. rear ends arran ed 'in parallel relation to the ground, sai rods .being serpentine in shape with the' serpentine portions thereof `parallel throughout.
